James, thankfully, did not have to wait long for a response to come up from his class. Patience was not a virtue that James possessed, really, especially with children. Listening to the girl - a Ravenclaw by the colour of her tie - explain why she had picked up the potion made James nod along to show that she was, at least, on the right tracks in respect of the balm she had picked out.
Waiting for the girl to finish applying the balm, James motioned her away from the body, back to her seat. "For those of you close enough to see the body, you will see that the bruising has, indeed, started to fade from the body. Therefore, I will award 5 points to Ravenclaw for a correct solution in this case." James explained, trying the best he could to sound like a fair professor in the giving out of house points.
Even if he rarely did such a thing.
"Next." James continued, motioning to the open wound on the leg of the body. "How would anyone deal with a laceration, using a potion, of course?" He asked, looking around the room for someone else to bring an answer forward.
